COIN-CONTROL MECHANISM.

Specification of lletters Patent.

Application filed January 25, 1911, Serial No. 604,663. Renewed June 18,1915. Serial No. 34,968.

To all whom it may concern Be it known that I, CHARLES F.- BURK- HART, acitizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Coin-Control Mechanisms; and I do hereby declare the following to bea full, clear, andexaet description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to coin .control mechanisms and has for an objectto provide a coin control for use in association with the shoe dressingmachine and the shoe dressing delivering mechanism which forms thesubject matter of co-pending applications, filed January 24th, 1911.

A further object of the invention is to provide coin receiving contactswith electrically operated means controlled by the closing of suchcircuit through the coin for actuating means for holding the coin morefirmly in position.

Av further object of the invention is to provide improved means forshunting a fraction of the motor current through the coin for actuatinga solenoid switch for controlling the supply of energy to the motor.

A further object of the invention is to provide a coin chute with meansfor closing said chute and manually operable means for removing theclosure of the chute and, mechanical means for locking the closure in aclosed position at other times.

A further object of the invention is to provide an improved form ofmanually operated switch for restarting the motor after it has once beenstopped by a mechanical means.

A further object of the invention is to connect the said coincontrolling mechanism with the timing mechanism which forms the subjectmatter of the co-pending applications above referred to.

Vith these and other objects in view the invention comprises certainnovel construc tions, combinations and arrangement of parts as will behereinafter more fully described and claimed.

Fig. 1.2 is a perspective view of the timing mechanism.

Like characters of reference designate corresponding parts throughoutthe several views.

The improved coin control mechanism which forms the subject matter ofthis application is adapted for use in connection with the shoe dressingand shoe dressing delivering mechanisms described in the copendingapplications above referred to but is not limitedin its scope to suchuse and is operable with other mechanisms and for other purposes.

The mechanism is contained in a. housing 20 and preferably secured tothe front thereof and provided with a plate 21 which in turn, isprovided with a sight opening 22. At Fig. 2 the housing is shown withthe plate 21 in position while at Fig. 1 the housing'is shown with theplate removed disclosing the coin control mechanism. The plate 21 isprovidedwith a slot .23 communicating with the coin chute 24 which isprovided with any of the well known means for discharging coins otherthan that re- 7 quired, as for instance, the open side indicated at 25,whereby the coin when smaller than the right denomination in physicalarea is dropped from such opening into the cup 26 in position to beretrieved by the party depositing.

If the coin is of the right physical size it drops into a hopper 9?which directs the coin to drop between the contacts 28 and so i Fig.

' resistance 39 is introduced into the circuit leading tov the contacts28 and 29 so that.

29 which are visible :through the sight opening 22. The contact 29 ispivoted as at 30 'to swing and is controlled by a lever 31 and rod 32which extends to the rock shaft 33 which in turn is controlled by a rod34 extending to the timing mechanism which will be hereinafter morefully described.

The contacts 28 and 29 are in circuit through the lines 35 and 36 withthe source of electrical energy. indicated as 37 and also passes aboutthe coil 38'of a solenoid." A

only a fraction of .the motive force from the source of energy 37 passesto such contacts. The introductionof a coin indicated at 40 between thecontacts 28- and 29 will there fore energize the coil 38 to move themovable core 41 of the solenoid. The core is provided with an insulatingextremity 42 positioned to engage against the sides of the coin 40 andhold such coin firmly in engagement with the contacts 28 and 29 toprevent sparking and burning out the coin. It has been found byexperience that unless the coin can be held into firm engagement withthe contacts the sparking eventually burns out the coin and renders thecoin worthless. The core 41 also carries brushes 43 and 44 positionedfor engagement respectively with contacts 45 and 46 when the core hasbeen moved to position to clamp the coin as above described. Thecontacts 45 and 46 are respectively connected by means of lines 47 and48 with the source of electrical energy 37 and also with the motorindicated diagrammatically at 49 by use of which the mechanism isoperated. Introduced into the lines 47 and 48 is a switch indicated as awhole at 50 and which will be hereinafter more fully described.

The coin chute 24 is provided with a slot through which acurved arm 51extends so that when the arm 51 extends into and across the chute a coincannot be introduced through the slot 23. .The arm 51 is held yieldinglyto closed position by the spring 52 and ,is provided with a lever arm 53which has a knob or other convenient means for manipulating indicated at54 extending through a slot 55 in the front plate 21 in position to begrasped by the hand of the party operating.

When a coin is introduced into the slot 23 it is held back by the arm51. If now the lever 55 is manipulated by depressing the knob 54 the arm51 is raised from the chute to permit the coin" to pass. The springpromptly returns the arm to' position and as soon as the coin touchesthe contacts 28 and 29 the solenoid is energized to clamp such coininposition and toclose the contacts consisting of brushes "43 and 44 andcontact members 45 and 46. p The core 41 "also carries an arm 56 whichis rigidly se- BEST V LABLE com cured to a rod 57 positioned to engagebehind a finger 58 carried by the arm 51 so that when the solenoid isactuated the arm 51 is locked into the chute and retained in suchposition until the solenoid is deenergized and the core and arinreturned by the spring 59.

When the cycle of operation hasbeen completed the timing mechanism shownat Fig. 11 raises the rod 32 and moves the contact 29 to release thecoin 40 and also to o enthe switch shown at Figs. 7, Sand 9 todeenergize the motor and the solenoid. From the contacts 28 and 29 thecoin drops to the hopper 60 and through the chute 61 to a bag 62suspended upon the lower end of the chute by means of the chute beingformed with an enlarged head 63 about which the bag is tied as indicatedat 64.

The chute 61 extends into a casing 65 which islocked or otherwise.secured as may be required or desired and as indicated at Figs.

6 and 10. The object. of suspending the bag 66 carrying a plurality ofcams and actuated by a lever 67 and ratchet mechanism 68. A plurality oflevers 69 and 70 are pivoted as at 71, to the former of which levers therod 34 extends while the latter carries a rod 72 which extends upwardlyto. and operates the switch 50.

. The bracket 73 carries a cross-piece 76 upon which are spaced aplurality of contact members 77, 78, 79 and 80 connected respectivelywith binding posts 81, 82, 83 and 84 to. which are respectivelyconnected lines 85,

. 86, 87 and 88. Pivoted to the bracket 73 is a. U-shaped member 89carrying a cross-bar 90 which is provided with contacts 91 and 92, theformer of which is adapted to close the circuit between the contacts 77and 78 and the latter to close the circuit between the contacts '7 9 and80. The U-shaped member 89 is pivoted as at 93 and at such pivot is alsoarranged a bell crank lever 94 carrying a spring 95 positioned andproportioned to draw across the pivot 93 as the bell crank lever ischanged from the position shown at Fig. 7 to that shown at Fig. 8 toactuate the U-shaped member 89 to open and close the switchinstantaneously.
